Almost any lowering springs will "mess up" the camber to some degree but the less you go down the less the problem is. In fact many people have had zero noticeable effect from mildly lowering a Z. Mildly being no more than 1.5".
Lots to choose from. For what you need, here are my two suggestions:
Eibach Pro (very common choice) = -1" front, -1.2" rear (approx)
Tanabe (GF is stiffer than NF) = -1" front, -1.2" rear (approx)
Other good choices:
Hotchkis (also great deal if purchased as a kit with sway bars!).
Tein Luxury or S (Luxury has least lowering of any spring I believe).
And there are many others. Just DO NOT buy the slammed versions that lower more than 1.5" or you will have rubbing issues and will scrape your front end constantly etc.
